Taiga is the biome characterized by conifers.
The one major change that occurred was the placement and organization of the electron. Rutherford's model identified that the electrons were at a distance from the nucleus, Bohr's model identified that the electrons occurred at levels that related to their available energy, and the modern atomic model shows that electrons are located in a predicted area but cannot be identified in a specific point.
Cytoplasmic uses actin and myosin for the movement of the cytosol which causes the organelles to move inside the cell.
